The Bar30 High-Resolution 300m Depth/Pressure Sensor is a high-pressure, high-resolution pressure sensor that is sealed from the water and ready to install in a watertight enclosure on your ROV or AUV. With 0.2 mbar resolution, it has an amazing Depth measurement resolution of 2mm (with accuracy of + or - 50 cm) in the water column!
The sensor is the Measurement Specialties MS5837-30BA, which can measure up to 30 bar (300m/1000ft depth) and communicates over I2C. It operates on 3.3V I2C voltage but can accept power input up to 5.5V. It comes standard with a 4-pin DF13 connector that is compatible with most DroneCode compatible boards including the APM2.6, PixHawk, and others. The Bar30 High-Resolution 300m Depth/Pressure Sensor includes a temperature sensor accurate to ±1°C, with data also accessible through I2C. The anodized aluminum body is designed around the cable penetrator design and is compatible with all of the watertight enclosures.
